BTW, standard Collectors collect only results

Solr never discarded non-positive hits, and now Lucene 2.9 no longer
does either.
Hmm ... The code that I pasted in my previous email uses
Searcher.search(Query, int), which in turn uses search(Query, Filter,
int), and it doesn't return any results if only the first clause is
present (the one with negative boost) even though it's a matching clause.
I think this is related to the fact that in TopScoreDocCollector:48 the
pqTop.score is initialized to 0, and then all results that have lower
score that this are discarded. Perhaps this should be initialized to
Float.MIN_VALUE?
